DTH Hammer is often used in rock drilling projectshas a wide range of use in all kinds of hard and abrasive rocks, HFD's DTH Hammer has the following features:
1.New products designed based on mining condition, improved by advanced by advanced technology.
2.International High-Standerd materials with advanced process guaranteed quality.
3.Enhaced hardness to expand the life of hammer, and lower the using cost.
4.The modern theory is adopted in the structural design,faster drilling rate, which makes the stress wave duration longer, the stress amplitudeis, and the piston life is long.
